Heredofamilial amyloidosis, unspecified

This code signifies a genetic disorder characterized by the abnormal deposition of amyloid proteins in various tissues and organs, leading to progressive organ dysfunction. It encompasses inherited forms of amyloidosis where the specific gene mutation or protein type has not been identified or documented.

Assign this code when documentation indicates a diagnosis of heredofamilial amyloidosis without further specification of the type (e.g., transthyretin-related, gelsolin-related). This is appropriate when the genetic basis is known to be inherited, but the precise molecular defect is not yet determined or recorded.

• Do not use this code if a more specific type of heredofamilial amyloidosis (e.g., E85.0, E85.1) is documented.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it contributes to the patient's overall condition.
• Query the provider for specificity if "familial amyloidosis" is documented without further detail, to determine if a more precise code is available.
